Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows: referring to fig. 1, the accurate quantitative fluid conveying device comprises a storage tank 1, a controller 2, a liquid discharge pipeline 3 and a liquid inlet pipeline 4, wherein a storage cavity 5 is arranged in the storage tank 1, a liquid inlet 6 is arranged at the top of the right side wall of the storage tank 1, a liquid discharge port 7 is arranged at the bottom of the storage tank 1, the liquid inlet 6 and the liquid discharge port 7 are communicated with the storage cavity, the liquid inlet pipeline 4 is connected with the outside of the liquid inlet, the liquid discharge pipeline 3 is connected with the liquid discharge port 7 through a movable joint 8, a first electromagnetic valve 9 is arranged on the liquid discharge pipeline 3, a second electromagnetic valve 10 is arranged on the liquid inlet pipeline 4, and the first electromagnetic valve and the second electromagnetic valve are connected with the controller;

the top of the storage tank is provided with two mounting holes, each mounting hole is internally provided with a connecting rod, the bottoms of two groups of connecting rods are inserted into the storage cavity, each connecting rod comprises a first connecting rod 11 and a second connecting rod 12, the bottom of the first connecting rod 11 is provided with a low liquid level sensor 13, the bottom of the second connecting rod 12 is provided with a high liquid level sensor 14, and a vertical space is arranged between the low liquid level sensor and the high liquid level sensor; the low liquid level sensor is arranged close to the bottom of the storage cavity, the high liquid level sensor is arranged far away from the top of the storage cavity, and the high liquid level sensor and the low liquid level sensor are connected with the controller;

the liquid inlet is arranged right opposite to the high liquid level sensor;

a baffle 15 is arranged in a storage cavity of the storage tank 1, the baffle is arranged between the low liquid level sensor and the inner wall of the right side of the storage cavity, the bottom of the baffle is arranged close to the low liquid level sensor, and the top of the baffle is arranged below the left side of the liquid inlet; be equipped with a drain pipe 16 in the storage cavity, the drain pipe set up in the baffle with between the right side inner wall of storage cavity, the top of drain pipe with the inside of inlet links to each other, the bottom of drain pipe is close to the bottom setting of storage jar.

In this embodiment, use to add the washing liquid or add water to the circuit board cleaning machine as the example, can set up a bucket, be equipped with water or washing liquid in the bucket, the bottom of liquid inlet pipe all inserts in the bucket, and the middle part of liquid inlet pipe is connected with a suction pump, and the controller is connected with suction pump is automatically controlled. The end part of the liquid discharge pipeline is directly inserted into the cleaning machine, and quantitative liquid adding is carried out on the cleaning machine. In this embodiment, in the time of in-service use, after low level sensor detected the liquid level in low level sensor below, with data feedback to controller, the work of the air suction pump of controller control liquid inlet pipe way, the second solenoid valve is opened simultaneously, in sending the liquid of extraction to the holding vessel, after liquid adds a certain position, high level sensor detects after the liquid, explain highly being higher than high level sensor at the liquid in the holding vessel, the suction pump stop work of controller control liquid inlet pipe way, no longer add the liquid, controller second solenoid valve closes simultaneously, just so can guarantee that liquid no longer sends into in the holding vessel, guarantee the interior liquid ration of holding vessel, liquid height in the holding vessel is at high level sensor's position, be in high liquid level line, low level sensor then is low liquid level line. Then the controller control first solenoid valve opens, discharges the liquid in the holding vessel, when discharging to low liquid level line, explains quantitative liquid and discharges, and low level sensor detects, and first solenoid valve closes, then liquid pipeline work once more, so circulation, the volume that can guarantee every time the liquid feeding all is fixed. Therefore, the waste of fluid can be prevented, the amount of liquid adding at each time can be fixed, less liquid is prevented, more liquid is prevented, the cost is effectively reduced, and the processing quality of products is ensured.

Simultaneously, adopt the setting of baffle to through the setting of drain pipe, like this when the feed liquor pipeline send liquid, can send liquid into the bottom of storage jar through the drain pipe, because the bottom of drain pipe is close to the bottom of storage jar sets up, and the bottom of drain pipe probably is in low level sensor's below, and in the time of the feed liquor like this, liquid can not splash, guarantees to send the liquid quality, in the time of sending liquid moreover, can utilize the baffle to block, prevents that liquid splashes and influences low level sensor and high level sensor in the feed liquor, prevents the wrong report of police, guarantees the quality of liquid feeding.

Referring to fig. 1, the top of the first connecting rod 11 is connected to the top of the storage tank through a cam 17, the top of the second connecting rod 12 is connected to the top of the storage tank through a fixing plate 18, the second connecting rod is disposed on the left side of the first connecting rod, and the first connecting rod is disposed on the left side of the baffle. The height of head rod can adjust like this, also adjusts low level sensor's height promptly, also adjusts the volume of single tapping, is convenient for adjust the displacement, realizes the ration flowing back.

Referring to fig. 1, the liquid inlet pipe 4 is disposed below the right side of the outside of the liquid inlet 6, the top of the liquid outlet pipe 16 is connected with the inside of the liquid inlet through a bent pipe 20, and an anti-siphon hole 21 is disposed at an elbow of the bent pipe and disposed above the right side of the high liquid level sensor.

When liquid discharge in the holding vessel, its liquid level height can descend, because the effect of negative pressure, the inlet setting is in the top of storage jar moreover, can inhale the liquid in the outside feed liquor pipeline of inlet, leads to sending the liquid volume unstability, and not enough ration is through preventing the setting of siphon hole like this, can prevent siphonage's emergence like this, guarantees to send the ration and the accuracy of liquid.
